Hey

i'm running into a problem with the PDG service example:
$HH/help/files/pdg_examples/top_mayapipeline/mayapipeline.hip

Does anyone has an idea what could be the issue here?

I tested it with maya 2022 and maya 2024.

Getting the issue:
[16:38:37.646] ERROR: Failed with:
Traceback (most recent call last):
  File "C:\Users\Jonas\AppData\Local\Temp\houdini_temp\mayapipeline\pdgtemp\scripts\genericrpc.py", line 290, in _exec_script
    exec(compiled_block, l_dict, l_dict)
  File "<string>", line 6, in <module>
RuntimeError: Unsaved changes.


[16:38:37.646] ERROR: Task callback onCookTask failed

The issue might be because of running maya with an education version, but this has worked before tho.

Cheers
Jonas

You can use the USD native shader (Usd UV Texture) (or a vex shader) and put the texture path as a primvars on the agents.
In the material you can read the texture path from the string primvar and this should alter the textures with enough artist control.

Create a material builder and dive in. There you can create a principle shader or any other vex related shaders .
The new workflow is a little more container like.

Hey @PeterMandk

currently it's not possible to use custom point or prim attributes (which are be promoted) with the feather procedural.

What you have to do currently (as a work around) is to create the "custom" attributes as barb attributes e.g. using an uncondense and then a match condense node which creates these barb attributes.
This enables you to use colors on the barbs to create texture like patterns too.

I've edited this in your hipfile and attached it below

I already created an RFE for better control of attribute promotion (like point & primvars).

Cheers
Jonas



If you want to dive deeper in some of creating barb attributes take a look at the examples i build for the hive

Hey @jsmack,

thank you so much for your responds. Yeah fair point, cranking the values up helped.
I was just testing up to refract 10, reflect 10 cause I wasn't considering that the light would bounce that much.

That's a good point, and makes totattly sense now.
Think in a production scene i would probably overwrite the limits just on the object with a geometry settings node then.

Thanks for the help!

Cheers
Jonas

Hey,

i'm struggeling getting a proper "thin" glass material working with Karma.
I tried to extrude a simple grid

and added a MaterialX Shader.



Ive added a simple Dome Light and enabled render Light Geometry for the test.

When rendering with Karma, it feels like there's kind of self shaddowing happening inside of the glass, which leads to the black sides.

When rendering the exact same setup with vray, it does the proper side refraction too:



Additionally when i increase the thickness of the extrusion to around 1, karma does proper refractions on the sides of my geo too.
Did i miss a specific setting or is this a bug in the renderer?

I'm looking for the Karma equivalent to the geometry toggle "Enable True Displacement" for mantra.
In mantra it was possible to toggle and disable it to only apply bumpmapping based on the displacement and not the whole displacement. (vm_truedisplace)
Is it possible to achieve the same thing with karma?

Was a nice ride and cool to use different tools which are not usually in my dailiy toolkit but sometimes hard to find the strength and motivation after a long work day.
But it was a nice experience getting something out everyday and not iterating to long on the same things (eventho a lot of my entries could need some more iterations).

Thanks for the fun activity. And kudo to all participants and winners.

Shaders could be a litte more tweaked and the ripple surface could get some more max clamping but
for a fast shot i like the result
